LOUIS OHEVALLIER, OF BROOKLYN, NEIV YORK.

TOOTH-BRUSH.

SPECIFICATION forming part of Letters Patent No. 264,624, dated.September 19, 1882.

' Application filed March 21, 1882. (N model To all whom it may concern:

Be it known that 1, Lotus CHEVALLIER, a citizen of the UnitedStates,residing at Brooklyn, in the county of Kings and State of NewYork, have invented new and useful Improvements in Tooth-Brushes, ofwhich the following is a specification.

This invention is especially adapted to tooth brushes, but also to otherbrushes with handles, and is an improvement on the brushes described inLetters Patent of the United States granted to me September 13, 1881,No. fZeLLOlZ.

The objectof myprescnt invention is, among others, to simplify orcheapen the manufacture of the brushes and impart thereto the requiredstrength; and it consists in the combination, with a brush having ahandle projecting from the back thereof, of an elastic bulb arranged onthe handle and a water-feed tube which opens into or among the bristlesof the brush at one end and communicates with the bulb at its oppositeend. Such tube is arranged by preference on the exterior of the back andhandle, and extends through the handle in an oblique direction at theend where it communicates with the bulb, thus allowing the inner end ofthe bulb to be brought opposite to a plain or stnoth portion of thehandle. In order to give the bulb a superior hold upon the bandle, it ismade open at both ends, and the hair dle is passed entirely through it.This invention is illustrated in the accompanying drawings, in whichFigure l represents alongitudinal central section. Fig. 2is a top view.

Similar letters indicate corresponding parts.

The letter A designates the back of the brush, having the bristlesapplied thereto in any usual or suitable manner, and B the handleprojecting from the back.

O indicates the elastic bulb, and D the waterfeed tube. In a centralportion of the back is formed a hole, e,through which the tube D extendsat one end,so that such end is open to the mass of bristles. The tubeextends from the point referred to along the back and a portion of thehandle on the exterior thereof, and

thence through the handle in an oblique direction to the interior of thebulb, thus communicating at its outer end with the bulb. Openingssuitable for receiving the handle are made at two points and obtain adouble bearing, the inner end of the bulb being upon the plain portionof the handle without or next to the place at which the tube enters thehandle in its oblique passage through it.

By the employment of the tube D, I avoid the necessity of boring thehandle atits junction with the back, and thus leave the articlepossessed of the required strength at thatpoint,

while I am also enabled thereby to manufacture the brushes with facilityand at low cost. The oblique passage of the tube through the handle,moreover, by allowing the inner end of the bulb to be brought upon theplain portion of the handle referred to, is favorable to a tight. jointbetweenthe bulb and handle. The double bearing of the bulb obviouslygives the same a superior hold on the handle, and hence it is leastliable to slip or work off.

What I claim as new, and desire to secure by Letters Patent, is-- 1. Thecombination, substantially as hereinbel'ore set forth, with the brushhaving a handle projecting from the back thereof, of the elastic bulbarranged on the handle, and the water-feed tube on the exterior of theback and handle, opening into the mass of bristles at one end andcommunicating with the bulb at its opposite end.

2. The combination, substantially as hereinbefore-set forth, with thebrush having a bandle projecting from the back thereof, of thewater-feed tube on the exterior of the back and handle, opening into themass of bristles at one end and extending obliquely through the handleat the other end, and the elastic bulb arranged on the handle incommunication with the water-feed tube and with its inner end upon aplain portion of the handle.

3. The combination,substantially as herein- 5 before set forth, with thebrush having a handle projecting iroln the back thereof, and with thewater-feed tube situated on the exterior of the back and handle, of theelastic bulb open at opposite ends and havingthe handle passed IOOWitnesses:
